Description

Technical Field

[0001] The utility model relates to the technical field of gluing, in particular to a tool for verifying gluing. Background Art

[0002] In recent years, the de-modularization of battery packs has gradually become a trend. In the past, multiple cells were stacked into a small module, and then multiple small modules were connected in series and parallel and stacked into a box to form a battery pack. The current de-modularization of battery packs is to stack all cells on the outside and over-extrude them to form a large module, and then the entire large module is pressed into the box, and the entire large module cell is glued to the bottom of the box with glue. In order to meet the requirements of the fastening connection between the large module cell and the box, the spread area of ​​​​the glue needs to cover at least 95% of the bottom surface of the large module cell, and the thickness of each area of ​​​​the glue must be within the range of 1±0.5mm. Specifically, if the large module battery cell is directly loaded into the box, the glue on the bottom of the battery cell and the bottom of the box will stick together, and the side of the battery cell is also fixed by the crossbeam inside the box. It is difficult to take out the battery cell at this time, that is, it is impossible to observe the glue pressing condition at the bottom of the large module battery cell. If the large module battery cell is forcibly taken out, the glue pressing track of the box and the bottom of the battery cell will be destroyed, resulting in the inability to obtain accurate glue pressing conditions, and the solidified glue on the bottom of the box is even more difficult to clean. Therefore, it is currently difficult to accurately verify the glue pressing condition between the large module battery cell and the box. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0037] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] Please also read Figure 1 , Figure 3 and Figure 6This embodiment provides a tool for verifying glue coating, including a frame 1, a pressing plate 2 and a driving mechanism 3.

[0040] Among them, a contoured surface 231 is provided on the pressing plate 2, and the contoured surface 231 is configured to imitate the bottom surface of the object to be loaded into the box body 4. For example, the contoured surface 231 is configured to be the same as the bottom surface of the large module battery cell, and the contoured surface 231 is configured to be used to extrude the glue layer together with the box body 4 through the diaphragm.

[0041] The driving mechanism 3 is respectively connected to the frame 1 and the pressing plate 2, and is used to drive the pressing plate 2 to approach or move away from the box 4. When the pressing plate 2 is away from the box 4, it is convenient to move the box 4 to the bottom of the pressing plate 2. When the pressing plate 2 is close to the box 4, the contoured surface 231 on the pressing plate 2 will extrude the rubber layer together with the box 4. In this embodiment, the driving mechanism 3 is preferably a combination structure of a screw and a nut, wherein the nut is fixed on the frame 1, and the screw and the pressing plate 2 are connected. When the screw is rotated, the function of driving the pressing plate 2 to approach or move away from the box 4 can be realized.

[0042] During the verification, a layer of plastic membrane is first laid on the bottom surface of the box body 4, and then glue is applied. When applying glue, the number of glue tracks and the amount of glue applied can be increased from small to large. For example, the number of initial glue tracks can be set to 3, and the gap between each track can be designed to be equal. The amount of glue applied is designed to be 110g for the first time. After the glue is applied, a layer of plastic membrane is laid on the upper surface of the glue layer, and then the driving mechanism 3 drives the pressing plate 2 to approach the box body 4, and the contoured surface 231 on the pressing plate 2 is finally aligned with the box body. The bottom surface of 4 is separated by two plastic diaphragms to squeeze the glue layer together to spread the glue. After the glue is air-dried, take out the diaphragm and observe whether the glue pressing on the diaphragm meets the requirement of "the spread area of ​​the glue is greater than 95% of the area of ​​the profiling surface 231, and the thickness of the glue at each location is within the range of 1±0.5mm". If not, the number of glue tracks or the amount of glue applied is quantitatively increased (for example, the number of glue tracks is increased to 4, and the amount of glue applied on each track is 140g-150g), and the above process is repeated for verification until the requirements are met.

[0043] As can be seen from the above, the tooling using the technical solution can quickly verify the glue pressing situation, and the verification process will not damage the gluing track, so it has the advantage of high verification accuracy, and also greatly reduces the verification time and reduces the cost of verification. In addition, the solution can replace the pressing plate 2 with a corresponding profiling surface 231 according to different products, so as to quickly verify the glue pressing situation of various products, greatly improving the verification efficiency of gluing of various products.

[0044] See also Figure 2A pressure sensor 6 is connected between the pressing plate 2 and the driving mechanism 3. The pressure sensor 6 is used to collect the pressure value of the pressing plate 2. By observing the pressure value collected by the pressure sensor 6, the pressing plate 2 can more accurately simulate the pressure when the large module battery cell is put into the box, thereby further improving the accuracy of the glue coating verification.

[0045] Please also read Figure 1 , Figure 2 , Figure 4 and Figure 5 The pressing plate 2 specifically includes a guide seat 21, an adapter seat 22 and a profiling plate 23 which are fixedly connected in sequence, wherein a side of the profiling plate 23 facing away from the adapter seat 22 is the above-mentioned profiling surface 231, wherein a mounting seat 7 is connected between the pressure sensor 6 and the driving mechanism 3, in other words, the mounting seat 7 plays a role of adapter, so that the pressure sensor 6 can be connected to the driving mechanism 3, and the guide seat 21 and the mounting seat 7 are slidably connected along the driving direction of the driving mechanism 3, and the guide seat 21 plays a role of guiding the mounting seat 7, thereby improving the accuracy of the relative sliding of the pressure sensor 6 relative to the pressing plate 2, thereby improving the accuracy of the pressure value of the pressing plate 2 obtained by the pressure sensor 6.

[0046] Please read again Figure 1 , Figure 2 , Figure 4 and Figure 5 , a through guide groove 211 is provided in the guide seat 21, and the guide direction of the guide groove 211 is the same as the drive direction of the drive mechanism 3. The mounting seat 7 is inserted into the guide groove 211 to realize the sliding connection between the mounting seat 7 and the guide seat 21. The above-mentioned pressure sensor 6 is accommodated in the guide groove 211, so that the guide seat 21 not only has a guiding function but also has a protective function for the pressure sensor 6, preventing foreign matter or a large amount of dust from entering the pressure sensor 6, thereby improving the accuracy of the pressure sensor 6 during long-term use. Secondly, the pressure plate 2 also includes a pressure block 24, which is fixed on the adapter seat 22 and is also accommodated in the guide groove 211. Moreover, the pressure sensor 6 is located between the mounting seat 7 and the pressure block 24. By designing this pressure block 24, the pressure on the pressure plate 2 can act on the pressure sensor 6, so that the pressure sensor 6 can realize the function of detecting the pressure value of the pressure plate 2.

[0047] Please read again Figure 1 , Figure 2 , Figure 4 and Figure 5The pressing plate 2 also includes a limit block 25, which is fixed on the guide seat 21. A limit portion 251 extends from the middle of the limit block 25. The limit portion 251 is located above the mounting seat 7. When the pressing plate 2 does not move downward toward the box body 4, the pressing plate 2 will not separate from the mounting seat 7 downward due to its own weight due to the obstruction of the limit portion 251, that is, the mounting seat 7 will not leave the guide groove 211.

[0048] Please also read Figure 1 and Figure 3 The adapter seat 22 specifically includes a connecting plate 221 and a plurality of fixing plates 222, each fixing plate 222 is respectively connected to the connecting plate 221 and the profiling plate 23, and the guide seat 21 is fixed to the side of the connecting plate 221 facing away from the profiling plate 23. The adapter seat 22 of this structural design has the advantages of simple structure, light weight, low cost and can ensure the compressive stability of the profiling plate 23.

[0049] Please also read Figure 1 , Figure 2 and Figure 6 A support plate 5 is fixed at the bottom of the frame 1, and the top surface of the support plate 5 is used for abutting the bottom surface of the outer body 4, so that the contoured surface 231 of the pressing plate 2 can reliably apply pressure downward to the body 4, and the whole set of tooling does not need to be fixed at a specified position, which is convenient for operators to move the tooling to any position for use. In other embodiments, the frame 1 may not be provided with the support plate 5, and the frame 1 may be fixed at a specified position. In this case, the pressing plate 2 can also reliably apply pressure downward to the body 4.

[0050] Please also read Figure 1 and Figure 3 The frame 1 includes an annular frame 11, a plurality of columns 12 and a support plate 13, wherein the plurality of columns 12 are connected around the annular frame 11 and extend downward, the support plate 13 is fixed at the middle position of the annular frame 11, the above-mentioned driving mechanism 3 is installed on the support plate 13, and the above-mentioned support plate 5 is fixedly connected to the bottom ends of at least two columns 12 respectively. The frame 1 with this structural design has the advantages of simple structure, light weight, low cost, etc., which is convenient for operators to move the entire tooling to any position for use.

[0051] See also Figure 1 Two linear bearings 14 are fixed on the support plate 13, and the two linear bearings 14 are respectively arranged on two opposite sides of the driving mechanism 3. A guide rod 15 is passed through each linear bearing 14, and the guide rod 15 is fixedly connected to the connecting plate 221 in the above-mentioned pressing plate 2, thereby improving the movement accuracy of the pressing plate 2, ensuring that the pressing plate 2 can continuously apply pressure to the box body 4 in the specified direction, thereby improving the accuracy of the glue coating. In other embodiments, the pressing plate 2 and the frame 1 can also be connected by a slide rail and a slider to achieve the purpose of high-precision movement of the pressing plate 2 relative to the frame 1.
